Dismissing servant: Agreed upon! Maybe: 5. Some kind of social network at the outside.
You make a very good point. But for the purpose of the given list, I think that 5. somewhat negates the need for 1. and 3.. Or, to put it another way, 5. would be an alternative to 1. and 3. I would say that your 5. could be combined with 1. as having some kind of social network at the outside gives one more courage to leave or makes leaving much easier thus reducing a measure of the courage that one would otherwise need if one had no support system.
